When Ten was five her grandpa told her of her heritage as last member of the Kyuumei Tribe and told her "Do not just roll over and die Ten... No matter what you have to resort to, you must keep struggling to survive! Even if you have to crawl, your way along the ground you must not simply give up your life! Do whatever it takes to stay alive! If you can think of it, then do it! If there's no merit to being a woman, then become a man! If you don't have brawns then use your brain! Throw everything on the line and stay alive at all cost!" Ten survived in Kokuhi Village by ratting out passing travellers to thugs.

She is then given the room next to Mou Ki's. Mou Ki then interrogates Ten saying, "for someone close to the King like you to come here, could it be that you're here to act as the King's spy?" As Ten is about to use her blow pipe Mou Ki says it wont hit him. Ten is shocked that he knows about her blow dart. Mou Ki then apologizes saying to Ten it was a test, and that her reaction time is enough to tell it seems she really didn't know where Kyou Kai was sending her, and it wasn't a trap set by her.

Coalition Invasion ArcEdit
Battle of Kankoku PassEdit
She rushed into the thick of the Duke Hyou Army vs Zhao Army battle to reform and rally the Hi Shin Unit who had lost all semblance of order, and was simply scattered about.
They had gotten lucky by running into Den Yuu at the very edge. So they were then able to save the Bi Hei and Taku Kei units. She direct all the wounded to the Centre. And the Bi Hei and Taku Units to hold their position and wait for further orders. Her strategy was to advance forward to where Shin is, while spreading out points to the side so that they can search for their comrades. The Bi Hei and Taku units were the 10th so far.
When they finally made it to Shin, she had Hai Rou, Ryuu Sen, Suu Gen, Den Yuu, and Bi Hei support and cover Shin's advance. Then Kyo Gai, Den Ei, Ryuu Yuu, and Chu Tetsu, spread out to the flanks and hold off any enemy reinforcements. And all cavalry units to charge their respective enemy officers. Worried that Mangoku’s rant had dispirited Shin, she rebuked the estranged man, noting that while Qin’s actions at Chouhei were wrong, his, were far worse.
Following Mangoku’s defeat, she was forced to share a kiss with Shin, when he was knocked off the hillside by Duke Hyou. After which, she appeared self-conscious when Shin addressed her the following day. This does not last long however, as she is soon seen conversing with him regularly.

When the Hi Shin unit moves back to the front lines to help with village reconstruction and border security, she seasoned the food for the entire encampment. And when Kyoukai returns, boasting of her goal to give birth to Shin’s child, she takes her aside to explain just how embarrassing a statement it was.
Conspiracy in the Court Arc Edit
The 5,000 strong Hi Shin unite arrived just in time to save General Heki from the Joint Zhao and Rebel Armies' pincer, taking on the Zhao army of 10,000 alone. At Heki's concern she informed him of their growth, stating, "But y'know Heki... as expected, the one who has grown the most in these last two years... is Shin."
For the Siege of Tonryuu she decided to put Shin and Kyoukai together, under the basis that speed would be paramount in saving Seikyou's life. Upon confirming that Seikyou was innocent in a plot orchestrated by Ryo, she attempted to persuade the rebel forces that they have been tricked, requesting any information they might have of the royal prince's whereabouts. She then ordered men to inform Shin of the truth, and to capture Ryo's retainer Hokaku. Regrouped with Shin and Kyoukai, she directed them to Soushin Mansion, judging that it was the likeliest place for Seikyou to be held captive.
Fire Dragons of Wei Arc Edit
Called to aid General Tou, she is overwhelmed by Go Hou Mei's defenses, stating that, "there's not a single weak spot at all", remaining skeptical even as they begin Ou hon's plan.
The Hi Shin unit was tasked with breaking through one of three fronts, annihilating the Wei’s reserve units, and –along with the Roku O Mi army and Gyoku Hou Unit- simultaneously assaulting enemy headquarters on the afternoon of the third day. To those aims, Ten focused on thoroughly destroying the enemy units one at a time. This however, had drawn the eye of enemy commander Jun Sou, who recognizing her strength as a strategist, had her kidnapped in the heat of battle and delivered to Gaimou.
Brought to Gaimou, with her life on the line, Ten was faced with a single question, “what are your desires?” To which she answered, “I just want to help Shin fulfill his dream… I also wish to achieve happiness together with him,” suggesting that her feelings may go beyond the ‘little sister’ that Shin sees her to be. Gai Mou found this answer satisfactory and agreed to exchange her life for Jun Sou’s. Upon returning to Shin, she immediately begins hashing out strategic maneuvers.
